I was reading the man of ls and in the end it talks about the Exit status of ls. It says:



 Exit status:
 0 if OK,
 1 if minor problems (e.g., cannot access subdirectory),
 2 if serious trouble (e.g., cannot access command-line argument).


But the thing is that i don't understand what they mean by:




cannot access command-line argument




I have never encountered a situation where i could not acces the arguments passed to my program and i was searching on the web about this particular situation and i couldn't get many information other then this site
which wasn't really clear to me and i was unable to reproduce the error. I'm not sure if i'm miss understanding the MAN page



Ps: I'm not sure if I'm miss understanding the man page or it's a real thing to can not be able to access the arguments AND thanks in advance for your answers.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
